Why do 144 Hz monitors perform better than 60 Hz when it comes to screen tearing? (using without vsync or gsync)

I would think nvidia would have so many patents on this idea of gsync that AMD won't be able to provide a real alternative? Yes, I am also waiting for a 4k g-sync monitor... that would be sick! (although I might have to wait a long time)

I'm so glad i bought a VG248QE. Its been amazing for gaming with the best input lag on the market and it can use the lightboost trick for smooth gameplay in twitch shooters and soon ill be able to buy a board replacement to enable g sync on it, not to mention that the price was really cheap when i got it :P

The videos that Nvidia has put out showing their demo for g-sync look like they still have some stutter at times. Have you noticed that g-sync doesn't give a 100% perfectly smooth experience in some cases or is that a problem with the video they provided? Obviously the stutter is much less than normal, but I was hoping this would be a 100% smooth solution. (talking about when you can push over the 30 fps minimum)

View this in a stutterfree browser such as Chrome, and make sure it says a green "VALID" at the bottom. Use the primary monitor and make sure Aero is enabled, to see an accurate animation. This one uses interpolation to simulate. The real hardware version looks better, however, this is just a demonstration to show how variable framerates can be done without erratic stutters.

Yea... That doesn't work... still tears and stutters even when it says 60h, 60fps and green sync bar.
